A breakthrough experiment, published in the Proceedings of the National Academy of Sciences, offers compelling support for ...

The origin of the first living molecules on our planet has long been debated. However, recent experiments are revealing new ...

Life on Earth began in a world of volcanic eruptions, violent storms, and a toxic atmosphere. Yet somehow, from this chaos, ...

New experiments suggest RNA, life’s essential molecule, could have formed naturally on early Earth and even arrived from ...

The RNA world theory suggests that life on Earth began with RNA molecules that copied themselves. It’s believed this self-replication eventually gave rise over millions of years to DNA and protein, ...

New research shows how RNA, a key molecule for life, may have formed on early Earth using simple chemistry and materials delivered by asteroid impacts, linking space science with the origins of life ...
